After all, this wasn't Medical University. When Song Yun finished the experiment, she would still have to cross the street to go back to the University. Song Yun was introverted and not very brave, so it was better to be cautious to prevent any accidents.
Only after Song Yun had agreed did Jiang Yue and Xue Yan leave.
The bus from the train station to either Medical University or the university's entrance usually stopped running at ten at night, and it was already half-past ten. Therefore, Jiang Yue and Xue Yan took a taxi to the train station.
Yao Xi happened to be coming out of the train station, holding a bag in one hand and a plastic bag in the other. The plastic bag contained a bottle of water and some snacks. Seeing them, he immediately smiled and said, "Didn't I tell you not to pick me up? I'm a guy, and I know where your school is. All I have to do is take a taxi and have the driver drop me off."
